To all whom tt may concern:

citizen of the United States, and resident of Brookline, inA the countyof Norfolk and State of Massachusetts, have invented new Thisnvcntion'relatcs to exhib iting appasection, of'an apparatus forexhibiting the The working parts of t-he apparatus are frame A. Mountedon the casing A is a' oot form B, which hol ls the stocking to lbetested. T-lie form B may be rigidly and immovably mounted on the casing,but is preferably movably mounted,'as by the pivot b, and is held tovery slight movement by a pair of opposed springs s, which yieldslightly in thus ease or cushion the blow to some extent.

At either side of the foot form B are hamoppositely arranged, dummyhands and arms E, E', which are pivoted to the case A thc relativeproportions and arrangements of the parts are such that the hammers whenswung on their pivots, travel in paths to strike the toe and heelrespectively the Patented Nov. 1, 1910.

foot form permissive blows, the paths or directions of the strikingblows of thetwo hammers being substantially opposed to each other. I Theoperat-ingmechanism illustratedin Fig. l consists of the reciprocatingbar l" mounted to slide lengthwise in= ide- 4ways provided inthesupports f, wlicgilz1 are secured within tliecasing A. Aniotor M,preferably an electric motor, is mounted' on the base of the casing, anddrives a pulley P by means ofa belt p. The pulley-P is, journaled onbracket p', and is provided with a pitinan yf-which actnates therciprocatin bar F ,tl1rou`gh the arin p. Latches C an 'C are mounted inthe casing on pivots c `and c, each latch adapted to engage a notch c2or c, providedlin a disk or plate e* secured to cach. arm about thepivot. Latch operating pins f2 are secured to the bar F, and the bar "Fis connected at its ends with the lower ends of the arms 'E and E byexible straps and f4, as shown. In the position shown in the drawingsthe bar F is shifted to its ing niec'anisin by which the bar F isconnected with the motor, causes the bar to start from the positionshown in the drawin toward the left, the arm E andhaininer will belifted away from the foot form B,

strap f*. At the same time the pin f2 Wifi move away from the lowerlever arm of latch C leaving the same free to drop into notch c when thenotch comes opposite the end of the latch. As the bar F approaches itsleft hand position, the arm E will be swun upward until latch C dropsinto note e, holding the arm E' and hammer D' in elevated position, andthe lefthand pin fz'will engage and swing the lower lever arm of latch(l, thus throwing the latch out of engagenient with notch c2 andpermitting the arm E and hammer D to fall and strike the toe of the footform. It will be understood that the strap f slackens during -the lefthand movement of' the bar F, since the n in E is held upright until thepin f2 Atrips the latch C, and hat the fall of the arm and hammer takesup the slack. The reverse movement of the reciprocating bar F opelatesas already described, first lifting arm E and .hammer D, andthenreleasino` ar E and hammer D and resetting arm anti hammer D again inthe position shown in caused alternately to strike the foot form.

It will be seen that the arms E and E' carrying-the hammers are pivotedat points sutliciently far removed from the foot. form 'foot form a,pereussive blow.

so that their strikino`r blows may be effected by gravity, since theii`centers of gravity never. pass outside of their pivotal centers.

when'the arms are raised to their highest points. Furthermore, when themechanism shown in Fig. 1 is used, each hammer is lifted out ofengagementwiththe foot form when the other hammer strikes its blow.

Referring' now to the form of operating mechanism shown in Fig. thereciprocating bar F andthe means for actuating the same may be asalready described; and the disks or plates c* having the notches e2 andes, serviiigas levers for lifting the arms and hammers, may also besubstantially the same asl already described, save that the notches arelocated at the bottoinsinstead of the sides of the disks. Pivoted toeach end of bar F is a yielding latch g, normally held projected asshowh, by spring g', a stop g2.

limitin the extent of the upward movement of the il 2, the' bar F is atitsextreine right hand-position. As the bar F inoves toward the left,the right hand latch f engages notch e3 and lifts arm E and bzi'mmeLDaway from the foot form B, and the left hand latch g yields until -itpasses clear of the edge of notch e2 and snaps into* said notch. J ustbefore bar vF reaches its extreme left hand position, notch e3 which hasbeen swung upward by the movcmeiitof the bar, slips ott' the right handlatch g, aiid releases the arm E and hammer D', which fall by gravity,and the hammer D strikes the heel of the A similar action takes placewith respect to the arm -and haminerll and D when the bar F moves towardthe right, and' the'ha'mmers l) and D are caused alternately to strikepercussive blows upon the Vtoe and heel of the foot form, andAconsequently upon the' stocking held thereby, as the bar reciprocates,atliording a cons )icuous demonstration of the durability'of t e articlesubjected to such repeated percussion.

n-the form shown in Fig. 2 eaehhaininer rests against the foot form whentheother hammer strikes its blow, whereas inthe form shownin Fig.1`eachhammer is retch. `In the position shown in vFig.
